The Liebherr LTM 1060-3.1 has a 48 m long telescopic boom and offers enormous load capacities

Brilliantly designed ballast concept

At a total weight of 36 t and with a 12 t axle load, it includes a 5.5 t ballast, 16.00 tires, eddy current brake, 6 x 6 drive and a hook block. To offer the widest range of driving conditions, in particular at an axle load of 12 t, a special ballast plate configuration has been implemented in the design. Depending on the crane equipment and the required vehicle payload, the ballast carried may be 3.7 t, 4.3 t, 4.9 t or 5.5 t.

To increase the load capacity, 7.3 t of additional ballast is available so that the 60 tonne machine can be used with a maximum ballast of 12.8 t. Appealing to countries without the 12 t axle load restriction: The LTM 1060-3.1 drives at approx. 15 t per axle with maximum ballast.

Latest travel gear technology

Thanks to its compact dimensions, the three-axle machine can be manoeuvred easily, even if on-site space is tight. The 9.44 m long chassis is just 2.55 m wide, even with the 445/95 R 25 (16.00 R 25) tires. The turning radius measured over the driver's cab is just 7.58 m and the ballast radius remains within 3.54 m. A support width of 6.3 m is achieved with single telescoping sliding beams. Where space is tight, however, a reduced support width of 4.5 m or 2.3 m can also be used. At the touch of a button, the crane is levelled completely automatically during the support process.

The air activated disk brake innovated by Liebherr on a mobile crane provides also on the 60 tonne crane for increased safety and efficiency. In comparison to conventional drum brakes, they offer considerably greater braking force that remains consistent even at high brake temperatures. The much longer service life durations also contribute to efficiency. Another advantage of disc brakes is that changing the brake linings - equipped with wear indicators - is faster and easier.

The active, speed-dependent rear axle steering system from Liebherr, tried and tested many times over, is used in the LTM 1060-3.1. This reduces tire wear considerably. The driver has five different steering programs available that can be selected easily for a wide variety of driving situations.

The six-part 48 m long telescopic boom on the LTM 1060-3.1 is telescoped in and out easily via the tried and tested rapid action TELEMATIK telescoping system. With the 9.5 m to 16 m long swing-away jib, the 60 tonne machine achieves hoisting heights up to 63 m and boom radii up to 48 m. The swing-away jib can be attached at an inclination of 0°, 20° or 40°. For work in two hook operation, a second hoist gear and a 2.5 m assembly jib and a rooster sheave is available.

Ease of control with Load Sensing and LICCON2

In the hydraulic system, the electric "Load-Sensing" control ensures accurate work operations. Up to four movements can be actuated simultaneously. Depending on the requirements for the lifting task and of the crane driver, the slewing gear can be easily switched from "open" to "hydraulic locked".

The Liebherr LICCON2 crane control is used in the LTM 1060-3.1. Thanks to its modern and future-oriented control architecture, it facilitates adaptation to the continually growing needs of the market. A mobile, multifunctional control and display unit - BTT Bluetooth terminal - is provided for upgrade functions. This means that the crane can be supported easily and safely. The crane driver also has the option of attaching and removing the hook block on the crane bumper with visual contact via remote control of the hoist winch and the luffing cylinder of the telescopic boom.

The Liebherr LICCON2 mobile crane control also offers the option of simple and thus cost-effective conversion into a complete remote control system for the crane. Other than the relevant software on the crane, all that is required is a console with two master switches, which the existing BTT plugs into. A significant advantage for the crane operator is that the console can also be used for other cranes with LICCON2 controls programmed for remote control operation.
